一种基于信息熵的Internet宏观行为模型研究

Internet Macro-Behavior Modeling on Information Entropy

具有开放、分布式、不协作、异构、无中心控制等特点的Internet复杂系统的管理、规划以及新一代网络体系结构的设计都离不开对网络行为的充分理解。该文从系统科学的角度出发提出了Internet系统结构三维模型;并在该三维模型的基础上利用信息熵原理建立了用于分析Internet宏观行为的Internet系统信息熵模型,根据信息熵模型可以分析Internet各组成部分之间的相互作用关系以及它们怎样引起Internet的宏观行为;最后,给出了信息熵模型的有效性和稳定性定量分析的判别式,其中稳定性判别式可以作为Internet宏观行为的整体控制的一个重要依据。

Internet has become a complex system that has o pen,distributive,uncooperative,heterogeneous,non-center-control characteri stics.People manage and scheme Internet,and design new generation network arc hitecture need to perceive network behavior.This paper,in a system science vie wpoint ,puts forward three dimensions model about Internet architecture,and e stablishes an information entropy model about Internet on the base of three dim ensions model,which is used to analyse Internet macro-behavior,analyse the in teraction between parts of Internet and how to give rise to Internet macro-beha vior.At last,the paper offers tow formulas to verify the availability and sta bility of this information entropy model,and the second formula is also importa nt to control Internet macro-behavior.
